Maybe i've found the solution to my problem using API function SetTimer with TimerProc CALLBACK but i do not know how i can use it...i need an example to follow...

UINT SetTimer(
HWND hWnd, // handle of window for timer messages
UINT nIDEvent, // timer identifier
UINT uElapse, // time-out value
TIMERPROC lpTimerFunc // address of timer procedure
);

VOID CALLBACK TimerProc(
HWND hwnd, // handle of window for timer messages
UINT uMsg, // WM_TIMER message
UINT idEvent, // timer identifier
DWORD dwTime // current system time
);

to execute every 2000 msec my procedure TMyTimer.TimerEvent(Sender:TObject)

i'm trying to use this statement:
SetTimer(0, 0, 2000, addr(Timer1.TimerEvent(Timer1)));

but i get this error:
VARIABLE REQUIRED

???!?!?!?
where? when? why?
AAAAAHHHHHHHHHHHHHHHH
help me please!!!!
